GPS Car Speed and Position Logger / Monitor
The GPS Car Sped and Position Logger/Monitor is a full featured project that is based on NXP/Philips LPC-2148 ARM7 processor. I had to quickly make this for my land trip from Cebu to Bacolod and back last December of 2006.
I used a ready made hardware, the Olimex LPC2148 PCB, that was available at that moment. The board is then wired to a GPS receiver with the 3V supply and the GPS TX pin connected to one of the ARMs serial port.
The software is using a ported FreeRTOS for LPC2148 as its real-time operating system. And incorporates ChanFS file system for log data storage to a FAT16 formatted SD/MMC card.
It also includes code from LPCUSB and has a USB serial port emulation when plugged to the computer to monitor NMEA sentences on the PC. Aside from that, it can be booted up as a USB mass storage device to retrieve the logs without removing the SD/MMC card from the board’s slot.
The code can be compiled using WinArm GCC.
